Description
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to sheets and mattresses and, more particularly, to sheets that are form fitted to mattresses.

2. Description of the Prior Art

Presently, fitted sheets have elastic edges which fit over the sides of mattresses. The tension in the elastic material permits a tight fit of the sheet on the mattress. With time, however, and after undergoing numerous launderings in a clothes washer and numerous dryings in a clothes dryer, the elastic may lose its tension for providing a tight fit for the sheet on the mattress. In this respect, it would be desirable if a fitted sheet fit on a mattress without using elastic materials on the edges of the sheet.

Throughout the years, a number of innovations have been developed relating to mattresses and mattress coverings, and the following U.S. Pat. Nos. are representative of some of those innovations: 3,965,504, 4,809,375, 4,858,625, 5,070,557, 5,208,927, 5,263,212, and Des. 267,696. More specifically, U.S. Pat. No. 3,965,504 discloses a bedding assembly in which certain portions are connected together with zippers. However, there is no disclosure of using a zipper to attach a fitted sheet to a mattress.

U.S. Pat. No. 4,809,375 discloses a mattress that has a removable mattress cover that is attached to the mattress by means of a zipper. The mattress cover is attached to the top of the mattress and does not extend down the sides of the mattress. Therefore, the mattress cover does not serve as a fitted sheet.

Each of U.S. Pat. Nos. 4,858,625 and 5,070,557 discloses a bed covering that is attached to a mattress by means of straps. Such straps do not permit a blanket to be form fitted to the mattress.

U.S. Pat. No. 5,208,927 discloses a bedding apparatus that employs a zipper to connect a blanket to a sheet. However, a form fitted sheet is fitted onto a mattress using well-known elastic bands.

U.S. Pat. No. 5,263,212 discloses a form fitted sheet that is attached to a mattress using a plurality of tensioned straps that pass under the mattress. Lifting a heavy mattress can be a difficult and unwanted chore. In this respect, it would be desirable if a fitted sheet fits on a mattress without using straps that pass under the mattress.

U.S. Pat. No. Des. 267,696 discloses a contoured bed sheet that is not a fitted sheet on a mattress.

Still other features would be desirable in a sheet and mattress apparatus. It would be desirable if a non-elastic-containing fitted sheet snugly fit onto four sides of a mattress. Most times a person uses two sheets on a mattress, a bottom sheet and a top sheet. The person usually lies on top of the bottom sheet and under the top sheet. In this respect, it would be desirable if an upper and lower sheet were provided that are secured together with a zipper.

Thus, while the foregoing body of prior art indicates it to be well known to use sheets associated with mattresses, the prior art described above does not teach or suggest a sheet and mattress apparatus which has the following combination of desirable features: (1) does not use elastic materials on the edges of a sheet; (2) fits on a mattress without using straps that pass under the mattress; (3) provides a non-elastic-containing fitted sheet that fits snugly onto four sides of a mattress; and (4) provides an upper and lower sheet that are secured together with a zipper. The foregoing desired characteristics are provided by the unique sheet and mattress apparatus of the present invention as will be made apparent from the following description thereof. Other advantages of the present invention over the prior art also will be rendered evident.

SUMMARY OF THE INVENTION

To achieve the foregoing and other advantages, the present invention, briefly described, provides a sheet and mattress apparatus which includes a fitted sheet assembly which includes a fitted sheet portion and a first fastener strip attached to and substantially coextensive with an edge of the fitted sheet portion. A mattress assembly includes a mattress portion and a second fastener strip attached to sides of the mattress portion. The second fastener strip is substantially coextensive with the first fastener strip. When the first fastener strip is connected to the second fastener strip, the fitted sheet assembly is connected to the mattress assembly. The first fastener strip can be a first zipper strip. The second fastener strip can be a second zipper strip. A slider assembly, supported by the first zipper strip and the second zipper strip, is included for zipping and unzipping the first zipper strip with respect to the second zipper strip.

In accordance with a second embodiment of the invention, the first fastener strip can be a first hook-or-loop material strip, and the second fastener strip can be a second hook-or-loop material strip which is complementary to the first hook-or-loop material strip.

In accordance with a third embodiment of the invention, a cover sheet assembly includes a cover sheet portion and a third fastener strip attached to an edge of the cover sheet portion. A fourth fastener strip attached to a side of the fitted sheet portion of the fitted sheet assembly. The fourth fastener strip is substantially coextensive with the third fastener strip.

The third fastener strip can be a third zipper strip. The fourth fastener strip can be a fourth zipper strip. A second slider assembly, supported by the third zipper strip and the fourth zipper strip, is provided for zipping and unzipping the third zipper strip with respect to the fourth zipper strip.

The above brief description sets forth rather broadly the more important features of the present invention in order that the detailed description thereof that follows may be better understood, and in order that the present contributions to the art may be better appreciated.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to the drawings, a new and improved sheet and mattress apparatus embodying the principles and concepts of the present invention will be described.

Turning to FIGS. 1-4, there is shown a first embodiment of the sheet and mattress apparatus of the invention generally designated by reference numeral 10. In the first embodiment, the mattress apparatus 10 includes a fitted sheet assembly 12 which includes a fitted sheet portion 14 and a first fastener strip attached to and substantially coextensive with an edge of the fitted sheet portion 14. A mattress assembly 18 includes a mattress portion 24 and a second fastener strip attached to sides 22 of the mattress portion 24. The second fastener strip is substantially coextensive with the first fastener strip. When the first fastener strip is connected to the second fastener strip, the fitted sheet assembly 12 is connected to the mattress assembly 18. The first fastener strip can be a first zipper strip 26. The second fastener strip can be a second zipper strip 28. A slider assembly 30, supported by the first zipper strip 26 and the second zipper strip 28, is included for zipping and unzipping the first zipper strip 26 with respect to the second zipper strip 28.

In using the first embodiment of the sheet and mattress apparatus 10 of the invention, the fitted sheet assembly 12 has a first zipper strip 26 extending substantially along the entire edge of the fitted sheet assembly 12 adjacent to the fitted sheet portion 14. In addition, the mattress assembly 18 has a second zipper strip 28 extending substantially around four sides 22 of the mattress assembly 18. The slider assembly 30 is moved to the beginning of the second zipper strip 28. The beginning of the first zipper strip 26 is inserted into the slider assembly 30. The slider assembly 30 is pulled around the entire edge to the ends of the first zipper strip 26 and the second zipper strip 28. In this way, the fitted sheet assembly 12 is connected to the mattress assembly 18. To remove the fitted sheet assembly 12 from the mattress assembly 18, the slider assembly 30 is moved in the opposite direction to unzip the first zipper strip 26 from the second zipper strip 28.

Turning to FIG. 5, a second embodiment of the invention is shown. Reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In this embodiment, the first fastener strip is a first hook-or-loop material strip 34, and the second fastener strip is a second hook-or-loop material strip 36 which is complementary to the first hook-or-loop material strip 34.

In using the second embodiment of the invention, the first hook-or-loop material strip 34 on the fitted sheet assembly 12 is attached by finger pressure onto the second hook-or-loop material strip 36 of the mattress assembly 18. In this way, the fitted sheet assembly 12 is attached to the mattress assembly 18. To remove the fitted sheet assembly 12 from the mattress assembly 18, the first hook-or-loop material strip 34 is pulled away from the second hook-or-loop material strip 36.

Turning to FIGS. 6-7, a third embodiment of the invention is shown. Reference numerals are shown that correspond to like reference numerals that designate like elements shown in the other figures. In addition, a cover sheet assembly 38 includes a cover sheet portion 40 and a third fastener strip attached to an edge of the cover sheet portion 40. A fourth fastener strip attached to a side 46 of the fitted sheet portion 14 of the fitted sheet assembly 12. The fourth fastener strip is substantially coextensive with the third fastener strip.

The third fastener strip can be a third zipper strip 48. The fourth fastener strip can be a fourth zipper strip 50. A second slider assembly 52, supported by the third zipper strip 48 and the fourth zipper strip 50, is provided for zipping and unzipping the third zipper strip 48 with respect to the fourth zipper strip 50.

In using the third embodiment of the invention, the fitted sheet assembly 12 is first attached to the mattress assembly 18 using the first zipper strip 26, the second zipper strip 28, and the slider assembly 30. Then, the cover sheet assembly 38 is attached to the fitted sheet assembly 12. This is done by moving the second slider assembly 52 to the beginning of the fourth zipper strip 50. The beginning of the third zipper strip 48 is moved into the second slider assembly 52, and the second slider assembly 52 is pulled towards the end of both the third zipper strip 48 and the fourth zipper strip 50. In this way, the cover sheet assembly 38 is zipped onto the fitted sheet assembly 12. To remove the cover sheet assembly 38 from the fitted sheet assembly 12, the second slider assembly 52 is pulled in the opposite direction to unzip the third zipper strip 48 from the fourth zipper strip 50. Then, the cover sheet assembly 38 is separated from the fitted sheet assembly 12. When person uses the third embodiment of the invention, the person lies on top of the fitted sheet portion 14 of the fitted sheet assembly 12 and under the cover sheet portion 40 of the cover sheet assembly 38. As best shown in FIG. 7, the cover sheet portion 40 has an end side and a lower edge (not labeled). The end side of the cover sheet portion 40 extends directly upward from the lower edge of the cover sheet portion 40 towards the top of the fitted sheet portion 14 such that the end side of the cover sheet portion is positioned flatly against the end side of the fitted sheet portion. Preferably and as shown in FIG. 7, the third fastener strip 48 is coupled to the fourth fastener strip 50 in such a manner that a pulling of the cover sheet relative to the fitted sheet will create a tension force between the third and fourth fastener strips, but will not rotate the third fastener strip relative to the fourth fastener strip.

In a fourth embodiment of the invention, not illustrated in the drawings, the third fastener strip can be in the form of a third hook-or-loop material strip, and the fourth fastener strip can be in the form of a complementary fourth hook-or-loop material strip.

The components of the sheet and mattress apparatus of the invention can be made from inexpensive and durable cloth, metal, and plastic materials.

As to the manner of usage and operation of the instant invention, the same is apparent from the above disclosure, and accordingly, no further discussion relative to the manner of usage and operation need be provided.

It is apparent from the above that the present invention accomplishes all of the objects set forth by providing a new and improved sheet and mattress apparatus that is low in cost, relatively simple in design and operation, and which may advantageously be used without employing elastic materials on the edges of a sheet. With the invention, a sheet and mattress apparatus is provided which fits on a mattress without using straps that pass under the mattress. With the invention, a sheet and mattress apparatus provides a non-elastic-containing fitted sheet that fits snugly onto four sides of a mattress. With the invention, a sheet and mattress apparatus provides an upper and lower sheet that are secured together with a zipper.

Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that many modifications thereof may be made without departing from the principles and concepts set forth herein, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use.

Hence, the proper scope of the present invention should be determined only by the broadest interpretation of the appended claims so as to encompass all such modifications as well as all relationships equivalent to those illustrated in the drawings and described in the specification.

Finally, it will be appreciated that the purpose of the foregoing Abstract provided at the beginning of this specification is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application.
